July 13, 2015  Plants and bacteria make use of sunlight with remarkably high efficiency: nine out of ten absorbed light particles are being put to use in an ordinary bacterium. For years, ... read more

June 30, 2015  Electrical engineers have demonstrated a new way to harness light particles, or photons, that are connected to each other and act in unison no matter how far apart they are -- a phenomenon known as ... read more

June 24, 2015  Researchers have made a crucial step toward nuclear spintronic technologies. They have gotten nuclear spins to line themselves up in a consistent, controllable way, and they ... read more

June 17, 2015  Researchers have predicted, in theory, that superconducting surfaces can become topological superconductors when magnetic iron atoms are deposited on the surface in a regular ... read more

May 13, 2015  In the new era of quantum computers, many daily life applications, such as home banking, are doomed to failure, researchers say, adding that new forms of ensuring the confidentiality of our data are ... read more

May 12, 2015  Topological insulators are "strange" materials, insulators on the inside and conductors on the surface. They also have properties that make them excellent candidates for the development of ... read more

May 11, 2015  Rydberg atoms, atoms whose outermost electrons are highly excited but not ionized, might be just the thing for processing quantum information. These outsized atoms can be sustained for a long time in ... read more

May 5, 2015  Quantum computers are in theory capable of simulating the interactions of molecules at a level of detail far beyond the capabilities of even the largest supercomputers today. Such simulations could ... read more

May 4, 2015  Researchers have shown that defects on an atomically thin semiconductor can produce light-emitting quantum dots. The quantum dots serve as a source of single photons and could be useful for the ... read more

Apr. 28, 2015  Quantum particles behave in strange ways and are often difficult to study experimentally. Using mathematical methods drawn from game theory, physicists have shown how bosons, which like to enter the ... read more

Apr. 27, 2015  The 'holographic principle,' the idea that a universe with gravity can be described by a quantum field theory in fewer dimensions, has been used for years as a mathematical tool in strange ... read more

Apr. 23, 2015  Thermal imaging, microscopy and ultra-trace sensing could take a quantum leap with a new technique. Scientists used quantum correlated beams of light to overcome the fundamental detection limit of ... read more

Apr. 23, 2015  Scientists have created an electronic device so accurate that it can detect the charge of a single electron in less than one microsecond. It has been dubbed the 'gate sensor' and could be ... read more

Apr. 23, 2015  Analysing the large volumes of data gathered by modern businesses and public services is problematic. Traditionally, relationships between the different parts of a network have been represented ... read more

Apr. 15, 2015  Engineers bring perfectly secure information exchanges one step to reality. They have now designed the first all-photonic quantum repeaters -- protocols that ensure data can be carried reliably and ... read more

Apr. 14, 2015  Researchers have uncovered the first evidence of an unusual quantum phenomenon -- the integer quantum Hall effect -- in a new type of film, called a 3-D topological insulator. This discovery could ... read more

Apr. 13, 2015  Physicists have narrowed the theoretical limits for where the 'speed limit' lies for quantum computers. The findings, which offer a better description of how quickly information can travel ... read more

Apr. 10, 2015  Scientists have encoded quantum information in silicon using simple electrical pulses for the first time, bringing the construction of affordable large-scale quantum computers one step closer to ... read more

Apr. 9, 2015  Temperature is a statistical concept. Very small systems, consisting of a small number of particles, are not usually described statistically. Scientists have now measured how quantum systems reach a ... read more
